What was detected

Soprano pipistrelle (Pipistrellus pygmaeus) · 37 calls · 52.5 kHz · strongest 0.857
Nathusius' pipistrelle (Pipistrellus nathusii) · 4 calls · 41.1 kHz · strongest 0.627
Long-eared bat · closest match Plecotus austriacus of 2 · 2 calls · 16.1 kHz · strongest 0.251
Measured 16.1 kHz is far outside the expected range for this label. Flagged for review rather than corrected: this measurement is not precise enough to name an alternative. This is a protected species, so the claim is held back.
Noctule, Leisler's or serotine · closest match Nyctalus noctula of 3 · 2 calls · 22.7 kHz · strongest 0.444
